Align the reference and repeat images to sub-pixel accuracy
The second step is to multiply the two SLC images to form the complex interferogram
Extract the phase of the interferogram
This technique uses a combination of DInSAR produced by data pairs on a small orbital separation (baseline) in order to limit the spatial decorrelation
Possibly, more than one independent acquisition subset will be generated; thus, the latter have to be ‘linked’ each others.
Independent SAR acquisition datasets, separated by large baselines, are linked by the application of the SVD method, increasing the observation temporal sampling rate
